MATTRESS.

Application filed July as,

invention is to so com- The object of this and a spring mattress bine a box spring in a single structure of both will be preserved, and the bjectionable habit of mattresses to ex and laterally and so produce unsightly ridges will be eliminated. Further objects of this invention are to produce a mattress construction which will be very comfortable and which can be produced at a reasonable price.

In the accompanying drawing, Fig. .1 is a perspective view of a mattress embodying my present invention, a portion being broken away to show its structure. Fig. 2 is a longitudinal section of one end thereof.

Similar reference characters refer to like parts in both views.

Mattresses, whether of the usual pad type .or formed with enclosed springs, when placed usually increase in length and width to such an extent as to project considerably beyond the edges of thebox springs. The present structure has been so designed that this undesirable extension does not oocur,

The box spring shown in the drawing may be of any desired construction and consists of any desired number of hour-glass springs 1, mounted on a frame consisting of slats 2 and 3, or of any other desired construction. These springs may be spaced and united according to the practices of the trade and a layer 4 of burlap extends across the tops of these springs and may be stitched thereto, although any other means may be employed to hold the .upper ends of these springs in their proper positionl The practice of using heavier or stiffer springs at those points where the greatest be followed.

prefer to spread a layer 5 of felt onthe burlap 4, this layer being of any desired depth, from one-half inch to several inches in thickness according to the demand of the trade. On this layer of 'felt' is placed a second sprin structure consisting of helical springs 6, 'eac encased in a separate case or pocket 7,

these cases or pockets being connected at. their upper andlower ends to adjacent pockets. These springs are of com aratively large dgiimeter for them length an are quite flex- 1 e.

A layer 8 of tickin or other fabric extends over the springs 6 an down to the frame 2-3 and a layer 9 of felt or other elastic material is placed on this ticking, a cover 10 of ticking or other fabric covering this second layer of felt and also extending down to the rame, the two layers of fabric and the felt between them being preferably tufted. The lower edges of the two layers 8 and 10 of fabric are attached to the frame. I also prefer to secure these layers to the outer rows of'pockets.

7 midway their length, as at 12. The layer 9 of felt ma beof any desired thickness, but, because 0 the resilience of the springs 6, need not be as thick as the mattresses commonly in. use. I prefer to secure a layer of ticking (114; across the bottom of the frame to exclude ust.

Several layers of fabric may be substituted for the layer 5 of felt, so long as a flexible spacer between the two banks of springs is produced thereby. While I- have shown a layer 15 of fabric between the pad 5 and the lower ends of the spring pockets 7, this layer may be omitted if desired.

The details of construction and the proportions of the parts may all be changed by those skilled in this art without departing from the spirit of my invention as set forth in the following claim.

The usual reinforcements employed in boxsprin making, while not shown, will be made use 0 whenever necessary.

. I claim In a mattress construction, the combination of a supporting frame, a series of rows of upright springs mounted thereon, a layer of fabric attached to the upper ends of said springs, a layer of fibrous material on said fabric, a second spring structure mounted on said fibrous material and comprising cylindricalsprings and a cylindrical pocket for each spring, each of said pockets being attached to the adjacent pockets,

and a tufted.

pad mounted on said" second spring structure and comprising upper and lower sheets of fabric extending down to and secured to said frame and to the outer rows of said pockets intermediate the ends thereof.
